Technical Details

The WM7110IMS/RV uses a MEMS (Micro-Electro-Mechanical System) microphone element to convert sound waves into an electrical signal. It typically has a digital output, such as Pulse Density Modulation (PDM), which simplifies interfacing with audio codecs and processors. The microphone is designed for reflow soldering and is available in a small surface-mount package. Key specifications include sensitivity, SNR, THD, and power consumption. It is often used in arrays to improve directivity and noise cancellation. The IMS suffix refers to the packaging type, and the /RV suffix indicates that the microphone is supplied on Tape and Reel for automated assembly.
